I am trying to implement spike filters to avoid negative and unusually low and high values for pi points in PI AF.
I have using SQC analysis and other expression analysis for the same. I am getting results but the filtered value is always the same.
So, If the trend the raw value, I have set if values that vary with time but the filtered value is a straight line in a trend. Can somebody please help? Rick Davin
Idea is to have Filter analog input value to remove spikes and outliers using std deviation over the last 5 minutes. Here are snapshots of the analysis.
I hope this is enough to get some idea as to where i am going wrong. I am always getting same value for filteredval.
